Q21.
The ____ function is used to connect two front end channels.

a.

joining

b.

assembling

c.

bridging

d.

cooperative

Discuss
Answer: (c).bridging Explanation:The front end channels typically operate in different modes and bands. The bridging function is used to connect two front end channels. For example a standard radio can be bridged with frequency hopped radio using bridging function.
Q22.
____ messages hold setup information for digitally vocoded voice.

a.

Bitstream

b.

INFOSEC

c.

Modem

d.

Internetworking

Discuss
Answer: (d).Internetworking Explanation:Internetworking messages hold setup information for digitally vocoded voice, along with the type of vocoder, and the associated data rate. Internetworking also uses ACK, NACK, buffer management, and message forwarding functions.
Q23.
Which of the following is not an SDR function associated with presentation layer?

a.

Radio network configuration

b.

Encryption

c.

Virtual terminals

d.

Object request broker

Discuss
Answer: (a).Radio network configuration Explanation:Encryption, virtual terminals, object request broker for interconnecting applications are the SDR functions associated with presentation layer. The presentation layer provides translation and mappings with control code translations.
Q24.
Which of the following is not a responsibility of the data link layer?

a.

Framing

b.

Integration

c.

Addressing

d.

Error control

Discuss
Answer: (b).Integration Explanation:The data link layer is responsible for framing, physical addressing and error control. It also retransmits packet if necessary. The SDR functions include creation of point to point interface and adaptive quality management.
Q25.
Bitstream processing performs _____

a.

data encryption

b.

transmission termination

c.

connection tests

d.

frame alignment

Discuss
Answer: (d).frame alignment Explanation:Data encryption, transmission termination, and frame alignment are functions carried out by INFOSEC processing software. Frame alignment, bit stuffing and bit interleaving are functions of bitstream processing software.
Q26.
Which of the following is not a part of the channel encoder/decoder section in the functional model of software defined radio?

a.

RF/Channel access

b.

Source coding

c.

IF processing

d.

Modem

Discuss
Answer: (b).Source coding Explanation:The channel encoder/decoder section comprises of RF/Channel access, IF processing, and modem. RF/Channel access includes antenna and RF conversion. IF processing stage includes filtering, and frequency translation. Modem is responsible for waveform definition.
Q27.
____ may include digital beam forming.

a.

Modem

b.

ADCs

c.

Channel access

d.

IF processing

Discuss
Answer: (d).IF processing Explanation:IF processing may include filtering, frequency translation, digital beam forming, joint space time equalization, integration of space diversity and frequency diversity.
Q28.
____ connects sources that are physically remote from the radio node.

a.

INFOSEC

b.

RF/Channel access

c.

Network support

d.

Communication services

Discuss
Answer: (c).Network support Explanation:The sources, which are physically remote from the radio node, are connected via Synchronous Digital Hierarchy, Local Area Network or other networks to the radio node by service and network support.
Q29.
Joint control may grow towards autonomous selection of ____ and ____

a.

band, mode

b.

band, personality

c.

mode, personality

d.

personality, protocol

Discuss
Answer: (a).band, mode Explanation:Joint control may grow towards autonomous selection of band, mode, and data format. Joint control guarantees system stability, error recovery, and isochronous streaming of voice and video.
Q30.
_____ is essential to ensure that the required resources do not exceed the available resources of a radio platform.

a.

Joint control

b.

Host processor

c.

Host controller

d.

Evolution support

Discuss
Answer: (d).Evolution support Explanation:Evolution support is essential to ensure that the required resources do not exceed the available resources of a radio platform. It monitors the definition and download process of waveform personalities. It also verifies whether a personality is safe for activation.
